An international conference has opened in Bosnia-Hercegovina to try to resolve a dispute over one of the worst atrocities in the region during the Second World War.

Large numbers of Jews, Gyspies and Serbs died in Jasenovac camp, which was run by the Ustasha or Croatian Nazis. Although the camp was in Croatia many of its inmates were executed across the River Una in Bosnia. The Bosnian Serbs organised the conference in the town of Banja Luka to try to establish the truth between Yugoslav claims that more than six-hundred-thousand people were killed in the camp, and Croatian assertions that about sixty-thousand died.

A former Jasenovac commander, Dinko Sakic, was jailed for twenty years by a Croatian court last October for crimes against humanity.
